Enermax 400 Watt 2U Power Supply

Higher current output for use with demanding systems and for providing extra power to the Mass-Storage case. Features higher +3.3v and +5v for faster MB/CPU. Taller enclosure features large 80mm fan for reduced noise.

This version has been modified for reduced noise. Both fans slowed internally uses a 100ohm cable on the 60mm fan and 68ohm cable on the 80mm fan.
